I started testing the aio interface for ell and it seems to work, except 
it's not asynchronous. Turns out libaio works only under certain 
circumstances:
http://lse.sourceforge.net/io/aio.html
So it's useless. There is a newer alternative called io_uring, but only 
for newer kernels (5.1) and not available to my target system. I will go 
back to the POSIX AIO and use SIGEV_THREAD (writing an eventfd in the 
notify function) instead of SIGEV_SIGNAL.

Regards,
Simon
